Referring in detail to the drawings, the marking appliance of thepresent invention includes a plurality or set of cylindricalprice-marking stamps or rollers which are eac'h 'designated by thenumeral 30. Each oi the rollers 30, Figure 14, includes a suitablerubber stamp tread 3l which has a single price 32 repeated completelyaround its periphery, the figures being approximately the size ofstandard 2li-point type. Also, each gure or group of figures isunderscored, as at 33, Figure 2, and the figures are set far enough awayfrom the next gure or group of gures to obviate the possibility of thefigure or group of figures being read inversely, such as 61 instead of19, as shown in the drawings (Figure 2).

Each of the stamps or rollers 30 further includes an axle 34 which maybe made of any suitable material, such as metal, Figure 14, the axle 34extending through the center of the roller 30 and projecting beyond thesides thereof. The core or center 35 of the roller may be made of anysuitable material, such as wood, metal, plastic or rubber, and eachstamp or roller 30 further includes a suitable cushioning material 36which is arranged between the core 35 of the stamp or roller and thetread 3|, so as to permit the trea'd 3| to ride over the rims oi' cansand the like. If desired, the rollers 3B can be made completely out ofmolded rubber including the price-marking tread 3l. A separateprice-marking stamp or roller 30 may be provided for each common priceon any given commodity.

As an example, the following dimensions are use'd to illustrate theconstruction and proportions of one size of a roller 30. It is to beunderstood, however, that other sizes may be found appropriate formarking the articles. Each pricemarking stamp or roller 30 isapproximately 2% inches in diameter and 1% of an inch in thickness orlength, and all such stamps or rollers in the set should be of exactlythe same dimensions, although different sets may have differentdimensions. The complete set of price-marking stamps or rollers 30 ishoused or stored in a single container 3l',l Figure 16, and thecontainer 3l is constructed so as to allow' the price-marking stampor'roller 30 to stand on edge in itsvown compartment 38. Eachcompartment 38v is provided with openings or slots 29 which extend fromthe top so as to allow the protruding or projecting axles 34 on eachside of each pricemarking stamp or roller 30 to stand completely :freefrom any obstructions for a space of approximately 1%; of an inch aroundit and to be completely open on the upper side.

The marking appliance of the present invention includes an inkingroller, as shown in detail in Figure 15, and the inking roller includesa drum 39 having a screw-threaded, removable end 40, a felt or othersuitable material pad All being arranged around the circumference of thedrum 39. A suitable, detachable or removable screw filler plug or cap 42is provided for closing and forations or drilled holes 44 are evenlyspaced sealing the filler hole 43. A plurality of perforations ordrilled holes 44 are evenly spaced around the circumference of the drum39, so that ink can feed from the-interior of the drum to vthe inked padel. IThe holes lill are countersunk,

so as to provide a well which will enable ink to feed to the pad 4l, andthe pad il 4can be constructed of any suitable material, such as felt.The pad il is constructed so that it can be slid over the drum 39 whenthe end il is removed, so that the pad 4| can be easily and readilyreplaced. Axles 28 project from the drum 39, as shown in Figures 3 andl5.

VThe marking appliance of the present invention further includes asuitable handle 45 and the handle 45 includes a, center piece or bodymember d6, Figures 4 and 5, and a pair of similar, spaced, parallel,side-plates or pieces il and All', Figures 6 through 9. The pieces 41land 4l" are similar, so that a description of one will suce for both.The pieces 41 and 41' are connected to- -gether by means oiv screws 48,Figure 2, and a latch 49, Figures l and 11, is provided, whereby thefront end 50 of the handle 5 can be placed in the slot 29, Figure 16, sothat the'desired roller 33 can be picked up outof the container 31. Whenthe price-marking stamp or roller Eil is picked up, the roller axle 35is positioned in the slots l which are arranged in the front ends of theside pieces 41 and Ill', and the axle 34 abuts against the bearing 52.

The latch 49 is spring loaded by means of a spring 53, Figure 3, and thelatch 49 is pivotally mounted between the side pieces l1 and il by meansof a pivot pin 54.

The handle 45 further includes inclined slots 55, Figure 6, which arearranged in each of the side plates 41 and 41', and a bearing surface 56is provided at the inner end of each of the slots 55. rlhe bearingsurfaces 53 are adapted to receive therein the projecting or outer endsof the axles 28 of the inking roller 39. Latches 5! are provided forpreventing accidental movement of the inking roller 39, Figures 12 and13. Thus, one of the latches 51 is provided or connected to each of theside plates 41 and 41', the latches 51 being seated in a recess 48 inthe proper side plate. `llach of the latches 51 is provided with .theslots 55, Figure-3. The latches 51, forthe -inkingdrum are springAloaded Y,bye means` of 4springs 63 which are interposed between thepair of `ears 59.

The latch 49 serves to retain and selectively release the price-markingstamp or roller 3B, and a slot 64 is provided in each of the side platesi1 and 41', Figure 9, the slot 64 serving to receive therein the legs 65of the latch 49. Hooks 66 are formed on the front ends of the legs 65,and a trigger B1, Figures 10 and l1, is connected to the the rear end ofthe latch 49 for actuating the latch.

The marking appliance of the present invention is used as follows: Asuitable quantity of ink is poured into the inking drum 39, and then theller hole 43 is closed with the screw ller cap 42. The inking drum 39 isthen inserted so that the vends of its axle 28 descend into the guideslots 55 and the axles 28 are latched or locked in "a pair yof spacedears 59, and the ears 59 are 55 place by means of the latches 51. Thenthe front end 59 of the handle 45 is positioned or pressed into theguiding slots 33 in the Vcompartments in the container 31 whichv` housesthe price-marking stamp crroller desired. The priceemarking stamp orroller 39 is engagedandretained in the handle against the bearing 52 byAmeans of the hook end -65 of the latch 49. The Yroller 30 is heldagainst the inking drum 39 and its pad 4|. The prize-marking stampl orroller 30 is then rolled across the packages of merchandise to beprice-marked, as they stand in their case or shipping container, so thatwhole cases :of merchandise can be price-.marked in a few short motionsand with a minimum 'of eicrt. vWhen it is desired to release thatprice-marking stamp or roller 39 `vhich has been used, the trigger 51can be pressed and the roller '3G can be dropped f into the propercompartment in the container housing 31, so that another roller t'wcanbe picked up for marking other items with a different price.

From the foregoing it is apparent that a marking appliance has beenprovided wherein the rollers 39 each have a.Y single price repeatedaround its entire periphery, the pricesor numerals being suiicientlyseparated so that there will be no possibility of the numbers being readupside down, and wherein aset of the'rollers'll can be provided so thata separate stamp or roller Yfor each common price usedin the particularcommodity is provided. The container cr housing Slis especiallyconstructed so that the front end can be inserted in the proper slot to`engage the axles 36 of ythe price-marking stamp or roller which is to beused. Also, the roller 30 can be quickly released and returned to thehousing 31 after the user has finished with that particular roller.Also, the appliance of thepresent invention can be used for heading'columns in blank ledgers or notebooks or on blank sheets of ledgerpaper. The drum 39 is provid'edwith an annular recess 68, and the endplate 491s 'provided With an annular flange $9, Figure' 15, so that thepad 4l will be maintained initsfproper place, and also leakage of ink'will be prevented. The countersunk holes 44 provide a Well todistribute the ink to' the pad 42|' in the prdper amount. The rear endof thespring 53 'seats in a recess 10 inthe center piece or'body member45, Figure 4.
